Re: Lenovo G40-70 - only charging in Battery Protection Mode?

The system communicates with the batteries embedded electronics to determine charge status, rate of charge / discharge and even cell status (dead or dying).

My suspicion is that the battery itself may be on the way out (not charging correctly) due to faults in the charging board. I would try to reset the charging board using Lenovo tools, and if still not working replace the battery with known good.
